| Abstract |
A process for preparing a cyclic carbonate of formula II comprising reacting an epoxide of formula I over a catalytic system consisting of a zinc substituted polyoxometalate and a Lewis base at a temperature in the range of 100 150° C. and at 60 to 150 psig pressure of CO2 bringing the reaction mixture to room temperature and atmospheric pressure separating the catalyst to obtain the desired carbonate embedded image not shown
wherein R is selected from a halogen atom aliphatic and aromatic group. |
